The cast of the best picture winner were also outfitted in Calvin Klein for last night's Oscars.

Raf Simons, the newly appointed chief creative officer of Calvin Klein, is a big fan of Moonlight — and to show his appreciation and love of the film, the Belgian designer reached out to the cast for a collaboration that keeps on giving.

The first half of the collab took place at last night's big show, where Naomie Harris, Trevante Rhodes, Ashton Sanders and 12-year-old Alex R. Hibbert all wore custom Calvin Klein looks designed by Simons, marking his red-carpet debut for the American fashion house, which he joined last August. "I was honored to be able to work with the cast of Moonlight and to celebrate the incredible talent of each of these actors and the amazing body of work that the film represents," Simons said in a statement.

But the fun doesn't stop there. Simons also selected Rhodes, Sanders, Hibbert and best supporting actor winner slash brand-new dad Mahershala Ali (who opted for a custom Ermenegildo Zegna Couture tuxedo last night) to star in the brand's new underwear campaign. Added the designer of his decision, "It’s an acknowledgement of remarkable actors who are revealing something important of being a man today in what they do."

Creative director Pieter Mulier, who worked with Simons on his first denim campaign, which was unveiled earlier this month, noted that the campaign — which is a departure from previous, uber-sexy underwear ads starring hot young things like Justin Bieber and Lara Stone — is a new way of looking at the brand's historic relationship with the concept of masculinity. "Since the beginning, Calvin Klein’s underwear imagery has always made big statements about masculinity; the performances of these actors in Moonlight affected us deeply and made big statements about masculinity in a different way. Somehow we wanted to bring the two together." Like the denim ads, the underwear campaign was also photographed by Willy Vanderperre.

In a release, the brand emphasized the role of the actors' various ages (ranging from 12 to 43) in that definition of manhood and the coming-of-age concept.

In addition to Ali's acting award, the film also picked up the best picture win (in what was easily the most memorable Oscars moment of all time) as well as the award for best adapted screenplay. See select images from the campaign below.
